Ⅰ. Charging Misconceptions

Shocking Fact: Incorrect charging methods can reduce battery capacity by over 40% in just one year!

Three Harmful Practices:

Harmful PracticeConsequenceSolution

Harmful Practice Consequence Solution
Draining the battery completely Lithium dendrites pierce the separator Recharge at 20%-30% capacity
Leaving plugged in overnight Overcharging decomposes the electrolyte Set reminders to unplug after full charge
Charging in high temperatures 300% higher risk of thermal runaway Charge in air-conditioned rooms

Optimal Charging Strategy

  • Ideal Range: Unplug at 92% (e.g., stop at 58V for a 52V battery).
  • Recharge Threshold: Begin charging at 25% capacity.
  • Charger Selection:
  • ✅ Use manufacturer-provided chargers only.
  • Never use lead-acid chargers or non-lithium-specific chargers.
  • ℹ️ If the original charger is lost, choose a compatible one that matches the device's specifications.

Ⅱ. Long-Term Storage (>15 Days)

✅ Correct Method:

  1. Prep: Fully charge, then discharge to 50%-60%.
    • Why? Full storage causes oxygen releasebulging; and empty storage dissolves anode foilfailure.
  2. Maintenance: Perform a full charge-discharge cycle every 2-3 months ("activation").
    • Prevents over-discharge from self-discharge during inactivity.
  3. Environment:
    • Store in a dry, cool (<30°C), ventilated area (e.g., cupboard, shaded basement).
    • Avoid: Humidity → corrosion; heat (>45°C) → accelerated aging/thermal runaway.
  4. Safety Protocols:
    • Keep away from: Fire sources, chemicals (cleaners/gasoline), and metal objects (coins/keys).
    • Disconnect XT60 plugs to prevent micro-discharge.
    • Use opaque storage boxes to block sunlight.

🚫 Avoid:

  • Full storage → bulging
  • Empty storage → permanent damage

Ⅲ. Seasonal Solutions

Season Issue Professional Fix
Winter Range halves; sudden shutdown Preheat by charging for 5 mins → restores 90% range
Summer Overheating, incomplete charge Install aluminum heat sinks → keeps temp <45°C

Ⅳ. Safety Alerts

CRITICAL WARNING: Immediately disconnect, remove the battery, and seek help if:

🔴 Bulging: "Air-cushion" feel when pressed → cell expansion.

🔴 Sweet/Burnt Odor: Electrolyte leakage → combustion within 3 hours

🔴 Range Plummets: Full-charge range drops to 1/3 of normal → separator breach.

Hazard Risk Safer Alternative
Riding through puddles Water ingress → short circuit Install IPX7 waterproof covers
Emergency fast charging Overvoltage → PCB failure Use current-limited car chargers
Using after the crash impact Separator tear → self-ignite Post-crash X-ray inspection

Ⅴ. Emergency Response

Scenario 1: Overheating/Smoking During Charge

  1. Unplug the power.
  2. Spray with a Class D fire extinguisher (NEVER water!).
  3. Move to the outdoor concrete surface.

Scenario 2: Shutdown After Water Exposure

  1. Do NOT restart! Remove battery → Orient terminals downward.
  2. Blow-dry ports with cool air (hot air risks explosion!).
  3. Air-dry for 48 hours. If voltage <40V, seek repair.

Scenario 3: Sudden Shutdown & Reboot Failure

  1. Cool for 10 minutes.
  2. Clean terminals with alcohol wipes.
  3. Reconnect the XT60 plug.
  4. ⚠️ If unresolved: Suspect a PCB malfunction.

Integrate these techniques into every charge and usage habit to maximize safety and longevity!
